Im Bereich des Fußes des Turms in der Verlängerung der Achse des nach unten weisenden, zu montierenden oder zu demontierenden Rotorblatts 10 ist eine Seilwinde 12 angeordnet. Zwei über die Schultern der anderen, schräg nach oben weisenden Rotorblätter 10 gerührte oder in dem Bereich des Spinners der Gondel befestigte Einrichtungen 16 sind mit von diesen getragenen Umlenkrollen 18 versehen sind. Zwei von der - hier mit zwei gesonderten Seiltrommeln versehene - Seilwinde 12 aus- und einfahrbare Zugseile 20 sind über jeweils eine der Umlenkrollen 18 geführt. Eine Blattaufnahme 22 ist mit Mitteln 24 zum Befestigen der freien Enden der Zugseile, Mitteln 26 zum Umfassen des zu montierenden oder zu demontierenden Rotorblatts an wenigstens zwei voneinander beabstandeten Orten und Mitteln zum Führen des aufsteigenden Abschnitts der Zugseile 20 versehen.In the area of the base of the tower in the extension of the axis of the downward pointing, to be assembled or disassembled rotor blade 10, a winch 12 is arranged. Two devices 16, which are stirred over the shoulders of the other rotor blades 10 oriented obliquely upwards or fastened in the region of the spinner of the nacelle, are provided with deflection rollers 18 carried by them. Two of the - provided here with two separate cable drums - winch 12 out and retractable traction cables 20 are guided over one of the pulleys 18. A blade retainer 22 is provided with means 24 for securing the free ends of the traction cables, means 26 for gripping the rotor blade to be assembled or disassembled at at least two spaced-apart locations and means for guiding the ascending portion of the traction cables 20.

Zu Aufziehen eines Rotorblatts 12 werden zunächst die Einrichtungen 16 über die Schultern der beiden schräg nach oben weisenden Rotorblätter 10 geführt oder aber an dem Spinner der Gondel befestigt. sodann werden die Zugseile 20 um die Umlenkrollen 18 geführt. Die Blatttaufnahme 22 wird auf das aufzuziehende Rotorblatt 10 dieses gegen ein Verrutschen gesichert aufgeschoben, die einen Enden der Zugseile 20 werden an der Blattaufnahme festgelegt. Die anderen Enden der Zugseile werden durch die Führungen (28) der Blattaufnahme geführt und auf der Trommel (oder dem Trommeln) der Seilwinde (12) befestigt. Durch Betätigen der Seilwinde 12 werden die Zugseile 20 angezogen, die über die Umlenkrollen geführten Abschnitte der Zugseile 20 ziehen die Blattaufnahme mitsamt dem von dieser getragenen Rotorblatt nach oben bis in eine Position, in der das Rotorblatt (von dem Inneren der Nabe aus) an die Nabe angeschraubt werden kann.To mount a rotor blade 12, the devices 16 are first guided over the shoulders of the two obliquely upwardly pointing rotor blades 10 or attached to the spinner of the nacelle. then the traction cables 20 are guided around the pulleys 18. The Blatttaufnahme 22 is pushed onto the rotor blade 10 to be wound up against slipping, which are one ends of the tension cables 20 are fixed to the sheet holder. The other ends of the traction cables are guided by the guides (28) of the sheet receiver and mounted on the drum (or the drums) of the winch (12). By pressing the winch 12, the traction cables 20 are tightened, the guided over the pulleys sections of the traction cables 20 pull the sheet holder together with the rotor blade carried by this up to a position where the rotor blade (from the inside of the hub) can be screwed to the hub.

Bei der Demontage eines Blatts wird die Blattaufnahme entsprechend aufgezogen, wobei es sich auf das zu demontierende Rotorblatt aufschiebt. Nach Lösen der Verschraubung des Rotorblatts an der Nabe wird die Blattaufnahme durch Betätigung der Seilwinde abgelassen.When disassembling a sheet, the sheet holder is raised accordingly, whereby it defers to the dismantling rotor blade. After loosening the screw connection of the rotor blade to the hub, the blade holder is lowered by operating the cable winch.

Die Blattaufnahme 22 kann auch durch einen Rahmen gebildet sein, der mit einem Schwenkmechanismus versehen ist, welcher im Bereich des Schwerpunkts des das Rotorblatt aufnehmenden Rahmens an den Rahmen zu diesem um 90° verschwenkbar angesetzt und mit einer Ausbildung zur Aufnahme eines Kranhakens versehen ist, wie er in der DE 10 2008 033 857 beschrieben ist; eine solche Ausgestaltung der Blattaufnahme erleichtert das Verbringen des zu montierenden Rotorblatts aus der horizontalen Ausrichtung in die vertikale Aurichtung und umgekehrt das Ablegen des demontierten Rotorblatts.The sheet holder 22 may also be formed by a frame which is provided with a pivoting mechanism, which in the region of the center of gravity of the rotor blade receiving frame to the frame to this 90 ° pivotally attached and provided with a training for receiving a crane hook, such as he in the DE 10 2008 033 857 is described; Such a configuration of the sheet holder facilitates the movement of the rotor blade to be mounted from the horizontal orientation into the vertical direction and, conversely, the laying down of the dismounted rotor blade.

Bei dem dargestellten Ausführungsbeispiel bestehen die Mittel 26 zum Umfassen des zu montierenden Rotorblatts 10 aus zwei Elementen 26' und 26" die das Rotorblatt 10 in unterschiedlicher umgreifen. Diese Elemente 26', 26" sind mit Mitteln zum Führen des von der Seilwinde 12 zu den Umlenkrollen 18 verlaufenden Abschnitts des Zugseils 20 versehen (im einfachsten Fall schlichte Durchführungen, vorzugsweise aber Seilführungsrollen), was einem Pendeln des Rotorblatts entgegenwirkt.In the illustrated embodiment, the means 26 for embracing the rotor blade 10 to be mounted consist of two elements 26 'and 26 "which engage around the rotor blade 10 in different ways These elements 26', 26" are provided with means for guiding the cable winch 12 to the Deflection rollers 18 extending portion of the pull cable 20 is provided (in the simplest case simple feedthroughs, but preferably cable guide rollers), which counteracts oscillation of the rotor blade.
